A new species of troodontid theropod dinosaur identified, Albertavenator curriei, named after renowned Canadian palaeontologist Dr. Philip J. Currie.Palaeontologists initially thought that the bones of Albertavenator belonged to its close relative Troodon, which lived around 76-million-years-ago.This new species of troodontid in the Late Cretaceous of North America indicates that small dinosaur diversity in the latest Cretaceous of North America is likely underestimated due to the difficulty of identifying species from fragmentary fossils.
